The checks are carried out for real reinforcement inputted by the user. There are following checks available for all types of slabs and walls:

Ultimate Limit States

N+M

Shear

Interaction of shear and flexure

Serviceability Limit States

Crack resistance and crack width control

Stress limitation

Detailing rules

Check of reinforcement ratio

Check of the distance reinforcement bars

Slab/wall member can be reinforced by two layers of the reinforcement (by one or both surfaces) or the reinforcement bars can be placed arbitrarily. The checks are performed in (a) user defined direction, or (b) principal stress direction calculated for both surfaces and directions perpendicular to calculated directions, or (c) calculated direction of concrete compressive strut. The direction of concrete compressive strut is optimized for maximum utilization of concrete compressive strength. The calculation of design forces is based on Baumann’s theory.
